To all whom 'it moy concern:

Be it known that We, ROBERT It. HonoursoN end lsAAc J. SHIFLEY, citizens of the United States, residing et Chicago, in the county o Cool; and State oi illinois, have invented nenT sind useful lmproveinents in Eeves-Trough Cops, of which the following,f is e lull, clear, concise, end exact description, reference being had to the nccompeny ing druiving, forming u port of this specificetion.

Our invention relates to eaves troughs, suchns ere employed nt the eaves ot building roofs for carrying oil unter es is Well f known in the art, and pertains more purtihulnrly to end cops therefor. .ln structures of the prior nrt, such end cops -were constructed of two or more pieces of metal previously formed for their epplicotionto the trough and soldered together to 'forni-n unitary structure. Not only did such end cups require e greet amount of time, labor end expense in construction, but their application' to the eaves trough Wes necessarily complicated and required e greet amount of time. The end oep of our invention is constructed entirely of one piece of metal sind is formed into its ultimate shape upon the application thereof to the eaves trough. Not onlydoes the one-piece construction eliminate the disadvantages inthe construction of the rior nrt devices, but 'the 'feature of its being reshioned upon thetrough instead. of being previously formed und applied thereto, secures .in e convenient manner, :is wil hereinafter be Inode evident, extremely rigid sind permanent ettnchment.

ln the accompanying dreufings We lieve illustrated the end cap in its successive stages of development und also in its epplication to en eeves trough, it will be procticelly employed.

in these drawings, in which like reference chorncters ure applied to like parte throughf out the various heures, Figure l shows the blnnk i rom which the Cup is ilorincd 5 lligs. und 3 ilhistrute succeeding singes in the lonrnntion of thev cup; Fig. 4 is si seclionztl. vier-r on the line #lm-4 of. Fig. Cig. 5 is u r-:ectiouul `View on the line 5v5 ol Fig. il; und Fig. (i

shows n. portion of :in cuves trough with the fend cap ol' our invention opplied thereto.

The blank from which the ond cap is formed is indicated nt ll) und consists' oi the circular body portion l1, as indicated by dotted lines in Fig. l, und 'the extended portions l2 und 13 which in the formation ol the cup, ore fashioned into oppositely turned flanges. The blank is placed in suituble dies und is stumped or drown to assume the iorin shown 6( in Fig. 2. The extended portion l2 is turned upwardly outside the dotted line d to form the semi-cii'ounifercntiel Menge 12u. The eX- tended portion 13 of the blank is turned down- Wnrdly inside the dotted line d to form the semi-circuniferentiel llfingo 13 "l, The circuler body portion 1l has stamped therein, simultaneously, the diemelricnl crimp 1d es. clearly shown in Figs. 2 und el. After the structure has been thus fashioned. the body portion is folded upon itself over the crimp lei ond assumes the form shown in Figs. 3 und 5. When in this form it is reudy for its epplicetion to the eaves trough and when so applied is further folded und thus assumes th form shown in Fig. 6 sind in dotted lines in Figs. 3 and 5. When the body portion. is folded completely upon itself, that is, when it assumes the position shown in Fig. 6 und in dotted lines in Figs. 3 and 5, o semi-circuler 80 slot 15 remains between the respective semicircuinferentiel flanges end the end of thetrough is adapted to take into this slot. ln order to secure rigid attachment end Weterproo connection, it is advisable to pluce o smell amount of cement or similar material in the slot before the cop is clamped down into place.

When the cup is iirst properly placed in position upon the trough it is in the forni shown .in Figs. 3 and 5 und st smell amount oi' co ment muy then be applied. The portion of the bod f ll carrying the inner iin-inge 13a is then folded down to assume the position shown in dotted lines in Figs. 23 und 5, thus 95 securely chunpin the on. p to t hc cuves trou gh shown. in Fig". 6. The orni p lll prevents cracking when the structure is i'olded over and produces n nicely rounded odge 16.
